'MythBusters' gets an executive order from Barack Obama

The
"MythBusters" have already tackled the myth of the Archimedes solar ray -- but not to the satisfaction of the man in charge. As in, THE man in charge.

President Obama makes a special appearance on the Discovery Channel show on Dec. 8 to ask
Adam Savage and
Jamie Hyneman to give the myth another run. The notion is that the Greek scientist was able to use an array of mirrors to focus sunlight on Roman ships, causing them to catch fire.

Savage and Hyneman tested it out in a 2006 episode and declared the myth "busted," but fans -- including the president -- have wanted to see them give it another try.
